Procrastinate, procrastinate, procrastinate, cram cram cram cram cram!!

That's how I do it. I leave it all to the night before and then I pull an all nighter and I study study study. I study while driving to school, I study while walking to the class room, I study non-stop right up until they teacher hands out the test. Luckily I can retain 90% of the info I crammed on for the whole night/morning and spill it all out during the test. But once the test is over I won't remember most of what I was just tested on.

The method works for me.
